Where: Baden-Württemberg, Germany (47.7° N, 8.9° E: paleocoordinates 47.9° N, 7.8° E)

• coordinate based on political unit

When: MN 7 mammal zone, Upper Oehningen beds Member (Upper Freshwater-Molasse Formation), Sarmatian (12.7 - 11.6 Ma)

Environment/lithology: lacustrine - large; lithified limestone

• "Rising into massive mountains, as in the well-known Righi and Rossberg, they attain a thickness of more than 6000 feet. While they include proofs of the presenceof the sea, they have preserved with marvellous perfection a large number of the plants which clothed the Alps, and of the insects which flitted through the woodlands. They form part of a great series of deposits which have been termed “Molasse” by the Swiss geologists...By far the larger portion of these strata is of lacustrine origin. They must have been formed in a large lake, the area of which probably underwent gradual subsidence during the period of deposition, until in Miocene times the sea once more overflowed the area. We may form some idea of the importance of the lake from the fact already stated, that the deposits formed in its waters are upwards of 6000 feet thick. Thanks to the untiring labours of Professor Heer, We know more of the vegetation of the mountains round that lake during Oligocene and Miocene time than we do of that of any other ancient geological period.

• Plate 33, fig 5 in Knorr's "Oddities of Nature" is perhaps taken from this stone, based on its similar appearance.
